Abstract (en)
[origin: DE19904230A1] The invention relates to the use of phosphonous acid modified polyacrylates as sequestering agents in the production of aqueous bleaching agents. Preparations, preferably chlorine bleaching liquors, providing fabrics with reliable protection against yellowing can be obtained more particularly by adding polyelectrolytes, buffers and chlorine-stable surfactants.
